Thermal Processing in the Fertilizer Industry

• Thermal cycling • De-dusting Fertilizers and intermediate materials processed include: • Potash • Phosphate Rock • Monoammonium Phosphate (MAP) • Diammonium Phosphate (DAP) • Triple Super Phosphate (TSP) • Granular Triple Super Phosphate (GTSP) • Ammonium Nitrate (AN) • Ammonium Sulphate • Calcium Ammonium Nitrate (CAN)

The Manufacture of Sulfuric Acid and Superphosphate

In many other parts of the world it is more cost effective to use triple superphosphate fertiliser. In this process phosphate rock is reacted with phosphoric acid to produce a product with 21% phosphorous. Triple superphosphate plants are more capital-intensive but with a more concentrated product these plants can service a greater area.
